Referring to the Battle of Orgreave which happened during the 1980s miners strike, he added: “I promised the families the full truth about Hillsborough and I don’t believe they will have it until we have the truth about Orgreave.

“This force hasn’t learned and hasn’t changed.”

He also spoke about the judicial system and called for families to be given the same funding as public bodies for legal representation.

He said: “This, the longest case in English legal history, must mark a water shed in how victims are treated.”

Mr Burnham also said the country needed to do some “deep soul searching” after the verdicts.
